Which statement is a reason that modern human populations never reach Hardy-Weinberg equilibrium? (A)Evolution rarely occurs in human populations. (B)Mating is random in human populations. (C)Humans live in small, isolated groups. (D)Humans regularly travel all over the globe.

Answer:

The correct answer would be (D) Humans regularly travel all over the globe.

For a population to reach a Hardy Weinberg equilibrium it must follow conditions like:

  • The population size must be large.
  • Random mating must be practiced that is, selective mating or breeding should not take place.
  • No migration (immigration or emigration).
  • Events like natural selection, genetic drift, mutation et cetera which can change allele frequency should not take place.

Humans travel all over the globe sue to which immigration and emigration keep taking place in a population and prevent the population to achieve hardy Weinberg equilibrium.

The correct answer is (D)Humans regularly travel all over the globe.

Explanation:

Hardy-Weinberg equilibrium is a concept in biology that explains genetics in a population, in terms of allele and genes variation, remain constant except due to certain factors such as sexual selection, mutation, gene flow, among others. This effect has been proved in certain populations; however, in the case of modern human populations, this is not possible.

This can be explained due to multiple factors that include the fact that human populations are not isolated but tend to interact and these lead to gene flow as individuals from different populations reproduce as a result of migration, travel patterns, among others. Thus, one reason the modern human populations never reach Hardy-Weinberg equilibrium is Humans regularly travel all over the globe.
